Mapping random key-value pair of XML payload in Symfony2

[bentcoder]

Hi,

Well, I hope this is correct place to ask this question unless it is more relevant to Symfony!

Key randoms below can contain any key-value pair so whatever you feed in (as long as it is in value-key pair) will be accepted. e.g. <tomato>nonsense</tomato>. However my mapping doesn't pick them up so I get an empty array for randoms. What am I missing?

Note: I'm using "jms/serializer-bundle": "0.13.0", composer package with Symfony2.

PAYLOAD

<?xml version="1.0" encoding="UTF-8"?>
<product id="1">
    <title>Samsung</title>
    <randoms>
        <review>710</review>
        <popularity>good</popularity>
    </randoms>
</product>

MODEL MAPPING - I listed all public $randoms; below I tried.

namespace Application\BackendBundle\Model\Api\Xml;

use JMS\Serializer\Annotation as Serializer;

/**
 * @Serializer\XmlRoot("product")
 */
class Product
{
    /**
     * @Serializer\Type("string")
     */
    public $title;

    /**
     * @Serializer\Type("array<string, string>")
     * @Serializer\XmlKeyValuePairs
     */
    public $randoms;

    /**
     * @Serializer\Type("array<string, string>")
     * @Serializer\XmlKeyValuePairs
     */
    public $randoms = [];

    /**
     * @Serializer\Type("array")
     * @Serializer\XmlKeyValuePairs
     */
    public $randoms = [];

    /**
     * @Serializer\Type("array")
     * @Serializer\XmlKeyValuePairs
     */
    public $randoms;

    /**
     * @Serializer\Type("array")
     */
    public $randoms;

    /**
     * @Serializer\Type("array")
     */
    public $randoms = [];
}

JSON RESPONSE

{
    "title": "Samsung",
    "randoms": []
}

Issues barely get answers here but I hope someone answers this question!

You have defined the mapping of Randoms multiple times, you can only define this once as the last one will overwrite the previous ones.

I'm not sure its possible to set multiple accepted types in @Serializer\Type("array<string, string>")
Setting this annotation multiple times simple overwrites it.

There are a big number of open issues in https://github.com/schmittjoh/serializer/issues
So I don't think you will get an answer soon..

Also

    /**
     * @Serializer\Type("array")
     */
    public $randoms;

    /**
     * @Serializer\Type("array")
     */
    public $randoms = [];

This is really weird, if $ransoms must be an array set the default value to an array.

@sstok - As I noted in my question "I listed all public $randoms; below I tried.", they are for demonstration purposes to give you guys an idea what I've tried before so I actually have only one definition in my model which is:

    /**
     * @Serializer\Type("array<string, string>")
     * @Serializer\XmlKeyValuePairs
     */
    public $randoms;
